Andy, Yeah. I had to retype it in and thus the typos.

It's netmask 255.255.248.0 shown, not 255.255.255.248.

It would make a good reason but the numbers given are correct.  The netmask is the same as a /21.  192.168.131.21 is on his 192.168.128.0/21 network[1].  I notice he misspelled kernel though, with no network he had to type it in, it's still possible there is a mistake that he didn't notice and typed what he thought he saw.
